ABB渦流流量計FSS450

SwirlMaster FSS450 is the universal Swirl meter for high end flow applications. It uses a two-wire transmitter with leading edge DSP-Technology with advanced flow computer functionality. Signals from remote sensors like pressure, temperature, density or gas content can be computed directly with the signals from internal flow and temperature. Ideal for direct mass flow or standard flow of gases and liquids or direct mass and energy flow on saturated and overheated steam. 

Overview

Swirl flow meters can be utilized for highly accurate measurement of the flow of gases, liquids and steam over a wide range of temperatures in almost any application. Swirl meters are ideal for use on petrochemical raw materials, demineralized water and for direct, cost- effective steam mass flow by employing integral temperature measurement.

The SwirlMaster FSS450 is the advanced version with additional analog input for mass or energy flow measurement. Available with integral or remote transmitter with up to 30 m (98 ft.) cable length. Using optional inputs discrete flow computers are not longer needed in many applications.
